Description

Technical Field

[0001] This invention relates to the field of power equipment testing technology, specifically to an insulator temperature cycling test device. Background Technology

[0002] As a core component in power systems used for insulation and mechanical fixation, insulators often face the extreme effects of alternating high and low temperatures in their working environment. The thermal stress caused by temperature cycling can easily lead to problems such as cracking of the insulator skirts and failure of the bonding between the iron cap and the insulating parts, directly affecting the safe and stable operation of the power system. Therefore, the temperature cycling test of insulators is a key link in detecting their resistance to thermal shock and verifying product quality. This test needs to simulate the alternating high and low temperature conditions in actual service of insulators, and repeatedly immerse the insulators in hot and cold media at specified temperatures and switch them rapidly to assess the thermal stability and structural integrity of the insulators. The temperature control accuracy of the test equipment, the uniformity of heat transfer of the medium, the stability of sample fixation, and the transfer efficiency directly determine the accuracy and reliability of the test results.

[0003] Existing insulator temperature cycling test equipment mostly adopts a simple double-groove structure with a common suspended basket to carry out the test operation. Since the test basket is mostly an open frame structure, the insulator is usually placed directly at the bottom of the basket. During the test, the insulator is easily affected by the impact of the medium or the shaking of the equipment, which can cause the sheds to shake and collide, resulting in damage. In addition, the side walls and bottom of the basket only have simple through holes, and there is no directional flow design for the medium to enter and exit. When immersed, air can easily be trapped in the gaps between the insulator sheds, resulting in insufficient heat exchange and excessive temperature differences between different parts of the insulator. Furthermore, when switching between the grooves, the medium of different temperatures remaining in the sheds cannot be discharged quickly, which can easily lead to uneven local thermal stress and damage to the insulator samples, affecting the authenticity of the test. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an insulator temperature cycling test device to solve the problems in the prior art where insulators are easily impacted by the medium and collisions are caused, and air is easily trapped in the sheds during immersion in the medium, resulting in insufficient heat exchange.

[0006] Furthermore, the interior of the machine body is provided with a cold water tank and a heat preservation tank, and temperature sensors are installed in the cold water tank and the heat preservation tank respectively. The cold water tank is equipped with a circulating pump, which is connected to an external refrigeration unit. The insulation tank is equipped with multiple heating tubes.

[0007] Furthermore, the top cover includes multiple vertically arranged brackets, and anti-scalding doors and heat insulation plates are respectively installed between the multiple brackets. The anti-scalding doors are rotatably connected to the brackets via hinges, and handles are fixedly installed on the side walls of the anti-scalding doors. The inner wall of the heat insulation plate has grooves.

[0008] Furthermore, the transfer mechanism includes a first guide rail and a second guide rail, and the first guide rail and the second guide rail are arranged perpendicularly; The first guide rail includes a lead screw, the lower end of which is connected to the top of the machine body, and the upper end of which extends to the top cover. A first motor is installed on the top cover, and the output shaft of the first motor is connected to the lead screw through a coupling. A first slider is sleeved on the lead screw, and the sidewall of the first slider extends into the groove, and the width of the first slider is equal to the width of the groove. The second guide rail includes a base, a second motor is fixedly installed at the end of the base, and the second motor is mounted on the first slider. The second slider is sleeved on the base, and two sets of connecting rods are symmetrically arranged at the bottom of the second slider, and the two sets of connecting rods are fixedly connected to the top of the suspended basket.

[0009] Furthermore, the tray includes two symmetrically arranged positioning plates, which are located on the top of the assembly plate. Multiple horizontal plates are connected between the two positioning plates, and the multiple horizontal plates are equidistant from each other. Multiple through slots are opened on the multiple horizontal plates, and the positions of the through slots correspond to the positions of the shelves.

[0010] Furthermore, the shelf includes a ring base, with multiple pads arranged circumferentially on the upper end of the ring base, and two ear plates symmetrically arranged on the side wall of the ring base. The lower ends of the two ear plates are respectively fixedly connected to movable rods, and the movable rods are slidably connected to the cross plate. A spring is fitted onto the movable rod. The top of the spring is fixedly connected to the lower surface of the ear plate, and the bottom of the spring is fixedly connected to the upper surface of the cross plate. A sleeve is fixedly connected to the bottom of the movable rod.

[0011] Furthermore, the fixture includes a swing plate, one end of which is fixedly connected to an arc-shaped plate, and a rubber pad is provided on the side wall of the arc-shaped plate; a pin is installed on the other end of the swing plate.

The rack supports the insulator by its own weight, and a linked clamp below automatically clamps the insulator cap with an arc-shaped plate. This allows for tool-free, rapid clamping and positioning of the insulator, effectively preventing shaking or collisions during testing and transfer, ensuring sample integrity. Simultaneously, the equipment utilizes water inlets at the bottom of the basket, through-holes on the side walls, and water inlets and outlets. A guide plate, inclined between the inlet and outlet channels, facilitates rapid multi-channel entry and exit of the medium. The forced flow from the guide plate and fins propels the medium to fill the gaps in the insulator skirts and expels any remaining air, ensuring full contact and uniform heat conduction between the insulator and the medium. Furthermore, during tank switching, the equipment rapidly flushes out residual media of varying temperatures within the skirts, preventing uneven thermal stress that could cause insulator breakage and improving the accuracy of test data.

Therefore, they should not be construed as limitations on the present invention.

[0024] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0025] Please see Figure 1 and Figure 4This invention provides a technical solution: an insulator temperature cycling test device, comprising a body 1, a controller 2 for adjusting temperature and test cycles installed on the side wall of the body 1, the controller 2 having a built-in PLC control module and a touch screen, which can achieve closed-loop linkage control with various actuators and sensors of the device, and also has over-temperature, water shortage, overload fault alarm and emergency stop protection functions. The body 1 is equipped with a cold water tank 11 and a heat preservation tank 12, and temperature sensors are installed in the cold water tank 11 and the heat preservation tank 12 respectively. The temperature sensors are electrically connected to the controller 2. A circulation pump is connected to the cold water tank 11 and is connected to an external refrigeration unit to ensure the temperature control accuracy and temperature uniformity in the low-temperature range during the test. The heat preservation tank 12 is equipped with multiple heating tubes, and the heating power can be adjusted in stages according to the set high temperature parameters to achieve rapid heating and precise constant temperature control of the medium in the heat preservation tank 12, meeting the requirements of insulator temperature cycling test.

[0026] Reference Figure 2 , Figure 3 and Figure 5 The top of the machine body 1 is equipped with a top cover 3, which includes multiple vertically arranged brackets. Anti-scalding doors 31 and heat insulation plates 32 are respectively installed between the brackets. The anti-scalding doors 31 are rotatably connected to the brackets via hinges, and a handle is fixedly installed on the side wall of the anti-scalding doors 31. A groove 33 is provided on the inner wall of the heat insulation plate 32. It should be noted that the anti-scalding doors 31 adopt a double-layer door panel structure with embedded high-density heat insulation cotton, which enables flexible opening and closing, making it convenient for test personnel to load and unload insulator samples. At the same time, it blocks the heat exchange between the internal hot and cold tanks of the equipment and the external environment, reducing the energy consumption of the equipment operation.

[0027] Reference Figure 6 The top cover 3 is internally equipped with a transfer mechanism 4, which includes a first guide rail 41 and a second guide rail 42, which are perpendicularly arranged. The first guide rail 41 includes a lead screw 411, the lower end of which is connected to the top of the machine body 1, and the upper end of which extends above the top cover 3. A first motor 413 is mounted on the top of the top cover 3, and the output shaft of the first motor 413 is connected to the lead screw 411 via a coupling. A first sliding sleeve is fitted on the lead screw 411. Block 412, the sidewall of the first slider 412 extends into the groove 33, and the width of the first slider 412 is equal to the width of the groove 33. The second guide rail 42 includes a base 421, a second motor 422 is fixedly installed at the end of the base 421, and the second motor 422 is installed on the first slider 412. A second slider 423 is sleeved on the base 421. Two sets of connecting rods 424 are symmetrically arranged at the bottom of the second slider 423, and the two sets of connecting rods 424 are fixedly connected to the top of the basket 5.

[0028] Specifically, during the cyclic test of the insulator, the first motor 413 and the second motor 422 can be started respectively. The output shafts of the first motor 413 on both sides will drive the lead screw 411 to rotate simultaneously, thereby driving the sleeved first slider 412 to move. The groove 33 can accurately guide and limit the first slider 412 in the circumferential direction, preventing the first slider 412 from deviating or shaking during the movement. The distance between the second guide rail 42 and the cold water tank 11 and the heat preservation tank 12 can be adjusted as a whole. The second guide rail 42 can be used to adjust the horizontal position of the basket 5. The position of the basket 5 can be adjusted more flexibly, so that the basket 5 can be immersed in the cold water tank 11 or the heat preservation tank 12 in a short time.

[0029] Reference Figure 3 , Figure 7 and Figure 8 Below the transfer mechanism 4 is a basket 5 for placing insulators. Multiple through holes 51 are provided on the side walls of the basket 5. Two sets of water inlet channels 52 and water outlet channels 53 are respectively provided on the side walls of the basket 5, and both the water inlet channels 52 and water outlet channels 53 are located below the through holes 51. Multiple water inlet holes 54 are provided on the bottom plate of the basket 5, and the top diameter of the water inlet hole 54 is larger than the bottom diameter of the water inlet hole 54, which can control the water inlet speed and facilitate internal water exchange when the basket 5 is removed. The medium is discharged. Multiple assembly plates 55 are installed on the inner wall of the suspended basket 5. It should be noted that when the suspended basket 5 enters the cold water tank 11 or the heat preservation tank 12, the medium can first flow into the suspended basket 5 through the water inlet hole 54 at the bottom. As the suspended basket 5 continues to move, the medium is gradually injected into the suspended basket 5 through the water drain 53 and the water inlet 52. Finally, the medium flows completely into the suspended basket 5 through the through hole 51 at the top, ensuring that the insulator to be tested is fully immersed in the medium.

[0030] Reference Figure 9 and Figure 10 The suspended basket 5 has two equidistant support plates 6 inside. Each support plate 6 includes two symmetrically arranged positioning plates 61, which are located on top of the assembly plate 55. Multiple horizontal plates 62 are connected between the two positioning plates 61, and these horizontal plates 62 are equidistant from each other. Each horizontal plate 62 has multiple through slots, the positions of which correspond to the positions of the shelves 7. Multiple shelves 7 are equidistantly arranged on the two support plates 6. Further, in the above technical solution, one embodiment of the shelves 7 is as follows: The shelf 7 includes an annular seat 71. Multiple pads 72 are circumferentially arranged on the upper end of the annular seat 71. Two ear plates 711 are symmetrically arranged on the side wall of the annular seat 71. Movable rods 73 are fixedly connected to the lower ends of the two ear plates 711, and the movable rods 73 are slidably connected to the horizontal plate 62. A spring 74 is sleeved on the movable rod 73. The top of the spring 74 is fixedly connected to the lower surface of the ear plate 711, and the bottom of the spring 74 is fixedly connected to the upper surface of the horizontal plate 62. A sleeve 75 is fixedly connected to the bottom of the movable rod 73. It should be noted that when placing insulators on the shelf 7, the insulator's skirts are made to contact the pads 72. By maintaining a small contact area between the multiple pads 72 and the insulator, interference with the insulator during testing can be reduced. Under the influence of the insulator's own weight, the annular seat 71 will move downwards as a whole, thereby causing the movable rods 73 on both sides to move downwards synchronously. At this time, the springs 74 are in a compressed state, and the insulator can be stably placed on the shelf 7.

[0031] The aforementioned shelf 7 is only a preferred embodiment, which can achieve the effect of stable placement of insulators during the test, but it is not limited to this.

[0032] Furthermore, refer to Figure 11 Each of the multiple shelves 7 is provided with a clamp 8 below it. The clamp 8 includes a swing plate 81. One end of the swing plate 81 is fixedly connected to an arc plate 82, and a rubber pad is provided on the side wall of the arc plate 82. The other end of the swing plate 81 is equipped with a pin 83. A limit groove 811 is opened on the swing plate 81, and a support rod 84 is provided in the limit groove 811. Both ends of the support rod 84 are fixedly connected to connecting rods 85. The pin 83 is inserted through the sleeve 75. The top of the connecting rod 85 is fixedly connected to the lower surface of the horizontal plate 62.

[0033] Specifically, after the insulator is placed on the shelf 7, the sleeve 75 at the bottom of the movable rod 73 will cause one end of the swing plate 81 to move downward. Supported by the pin 83 in the limiting groove 811, the other end of the swing plate 81 will move upward, shortening the distance between the arc plates 82 at the ends of the two swing plates 81. The rubber pads on the sidewalls of the arc plates 82 tightly fit against the outer wall of the iron cap of the insulator, thereby achieving self-adaptive clamping of the iron cap of the insulator and further limiting the position of the insulator. This effectively prevents the insulator from shifting, shaking, or even tipping over due to factors such as medium impact or equipment shaking during the immersion and transfer of the cold and hot medium in the temperature cycling test, and prevents the insulators from colliding with each other. To address issues such as skirt damage and cap deformation, and to ensure the integrity of the test samples and the stability of the test process, a linkage limiting structure is formed between the clamp 8 and the shelf 7. No additional locking operation is required; the insulator is automatically clamped by its own weight after being placed in the shelf 7. After the test, the insulator is pulled upwards, and the movable rod 73 of the shelf 7 moves upwards under the elastic reset action of the spring 74. The sleeve 75 drives the swing plate 81 to reset, and the arc plate 82 releases the clamp on the cap, achieving one-click unlocking. The entire loading and unloading operation requires no tools, making the steps simple and convenient, significantly improving the efficiency of insulator sample clamping and unloading, and adapting to the temperature cycling test requirements of batch insulators.

[0034] Reference Figure 12 and Figure 13 Multiple guide plates 9 are detachably installed on the inner wall of the suspended platform 5. Furthermore, the embodiment of the guide plate 9 is as follows: The guide plate 9 is inclined, and multiple fins 91 are equidistantly arranged on its side wall. All fins 91 are arc-shaped. The guide plate 9 is positioned between the water inlet trough 52 and the water outlet trough 53, and the lengths of the guide plate 9 and the fins 91 are greater than the lengths of the water inlet trough 52 and the water outlet trough 53, which can completely cover the inlet and outlet channels of the medium. It should be noted that when the basket 5 is immersed in the cold water tank 11 or the heat preservation tank 12, the hot and cold medium rushes upward through the water inlet hole 54 at the bottom of the basket 5, and at the same time, it will also quickly enter the basket through the water inlet trough 52 on the side wall. Inside the basket 5, the inclined guide plate 9, together with the arc-shaped fins 91, forms multiple forced flow channels, which guide the incoming medium to the gaps in the insulator skirts. This forces the medium to fill each layer of the insulator skirts, thereby squeezing the air remaining in the gaps in the skirts upwards and expelling it from the top of the basket 5. This ensures that the medium can completely wrap around the insulator, allowing all parts of the insulator to fully contact the medium and achieve uniform heat conduction. This effectively avoids temperature differences caused by insufficient local contact with the medium, ensuring accurate and reliable test data for temperature cycling tests.

[0035] Furthermore, when the transfer mechanism 4 drives the basket 5 to switch between the cold water tank 11 and the heat preservation tank 12, new hot and cold media enter the basket 5. The flow-guiding structure formed by the guide plate 9 and the arc-shaped fins 91 will push the new media to quickly flush the insulator skirts, flushing out the original media of different temperatures remaining in the gaps between the skirts. This avoids the mixing of media of different temperatures in the skirts, which can cause uneven local thermal stress. This prevents damage such as skirt cracking caused by sudden changes in thermal stress, and ensures the integrity of the test sample. In addition, when the test is completed and the basket 5 is removed from the tank, the media remaining inside the basket 5 will flow out downward through the bottom water inlet 54 under the action of gravity, and the other part will quickly converge along the inclined surface of the guide plate 9 to the drain tank 53 for discharge, realizing the rapid emptying of the media and ensuring that the media in the basket 5 can be completely discharged, thereby improving the reliability of the equipment and the accuracy of the test results.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
